Technology in reverse...
By Nativescape
The 640 could/should have been so much better, had Garmin enabled the XM Weather capability in Automotive mode, in addition to the Marine mode, which does help XM Weather (WHY would they do such a stupid thing?!), and kept the Tracks/Tracks Management feature of the 276C/378/478 models, which are also geared toward Marine/Auto users. The unbelievable thing is that these missing features are all features that Garmin has enforced in older units - it is baffling why they would eliminate them in newer models, in particular at a time when this basic GPS functionality in the 640 is so widely available in smartphones. They also scaled down the number of saved Routes. As the 640 is presently configured, I will stick to my trusty 478 for a long time, in spite of the fact that I would have liked to upgrade to a larger screen and altered GPS receiver engineering found in the 640.

Garmin 640
By Robert F. Hoffman
I purchased this GPS as a back up to use on my boats and on land when required. I had contacted Garmin to make sure that the inland rivers were a percentage of the selective information base. When I received the unit and started using it I found the rivers were not on the unit. I then checked and found an update on the software was available. After reading the instruction, easy to understand, I hooked the unit to my MAC, with the provided cable, and down loaded the altered systemware and the river charts.
The unit meets my expected values at this point and I feel with more use, marine and auto, it will exceed my expectations.

Awesome GPS
By David Glover
So I purchased this unit for one purpose, to use it on boats in my boat club. I presently own a great deal of of Garmin's products, from nuvis on the street to a GPSMAP 4208 on my own boat. This is a great little GPS. I have been using it in the car until the weather warms up and I may use it in the boat. I would not commend using the included friction mount. RAM has an awful windshield mount that works great. As far as functions and usability, I have no issues, everything is where it is on my Nuvi in automati mode and marine mode on my GPS MAP 640. I have a G2 Vision card that I use in my 4208 and I put it in the 640 and I get all the further and added map features missing from the base map. For the reviewer who posted regarding the navigating function moving over land while in the water, that is because you need the G2 Vision card to use automati guidance. I would commend this GPS to others who need a portable GPS.
